ALSO ASKED IN Hitachi Vantara Network Security

This is a direct question meant to test your knowledge of network security management and determine if you are qualified to make recommendations to the customers of the firm you are interviewing with. You should answer this directly and succinctly.

"Sure, I'd be happy to. Symmetric encryption uses the same key at both ends of the packet transmission. The two processes involve encrypting and then decrypting the packet. Asymmetric encryption employs two different keys for the two processes. Symmetric encryption is faster but poses a bigger risk since the channel the packet is sent through is unencrypted."
